視角依存性色を呈し、複数の離散型伸長要素を備える有色ウェブ 本発明の有色ウェブ材料は前駆体ウェブ材料から作製され、前駆体ウェブ材料は下記のプロセスに従って処理されて、本発明の有色ウェブ材料を形成する。 Exhibits viewing angle dependency color, colored web material colored webs present invention comprising a plurality of discrete elongated element is made from a precursor web material, the precursor web material is processed according to the following process, colored present invention the web to form the material.

本発明の有色ウェブ材料は、単層ウェブ材料又は多層ウェブ材料を含むことができる。 Colored web material of the present invention may comprise a single layer web material or a multilayer web material.

一実施形態では、本発明のウェブは多層ウェブを含み、第一層は、第一屈折特性を有するポリマーを含み、第二層は、第二屈折特性を有するポリマーを含み、第一及び第二屈折特性は異なる。 In one embodiment, the web of the present invention comprises a multilayer web, the first layer comprises a polymer having a first refractive properties, the second layer comprises a polymer having a second refractive properties, the first and second refractive properties are different. このような多層ウェブ材料は、数百層を含むことができる。 Such multilayer web material can include hundreds of layers.

一実施形態では、本発明のウェブは、有色ウェブの少なくとも1つの層に干渉顔料を含む。 In one embodiment, the web of the present invention includes an interference pigment in at least one layer of colored web.

前駆体ウェブは、様々な所望の構造的特徴及び特性(所望の柔らかい手触り及び審美的に好ましい視覚的外観など)を有することができる三次元有色ウェブを形成するために、加工される。 Precursor web to form a three-dimensional colored web can have a variety of desirable structural features and properties (such as desired soft feel and aesthetically pleasing visual appearance), it is processed. 下記のように、本発明の有色ウェブを形成するために、多様なプロセスを利用することができる。 As described below, in order to form a colored web of the present invention can be utilized a variety of processes.

一実施形態では、本明細書に記載のプロセスから得られるウェブは、米国特許第7,402,723号及び同第7,521,588号に詳細に記載されているものと同様の伸長要素を備えることができる。 In one embodiment, a web obtained from the process described herein, a similar elongated elements to those described in detail in U.S. Patent No. 7,402,723 and ibid. No. 7,521,588 it can be provided.

本発明の有色ウェブ材料は、典型的には、開口近位端と開口又は閉口遠位端とを備える離散型伸長要素を備える。 Colored web material of the present invention typically comprises a discrete elongate element having an open proximal end and an opening or closed distal end. 離散型伸長要素は、所望により、離散型伸長要素の遠位端に、及び/又は、離散型伸長要素の側壁に沿って、薄化を呈することができる。 Discrete elongated element, optionally, the distal end of the discrete elongated elements, and / or, along the sidewalls of the discrete elongated element can exhibit a thinning. 多層前駆体ウェブについては、離散型伸長要素の遠位端における及び/又は側壁に沿った有色ウェブ材料の薄化により、薄化しているウェブの領域において、ウェブの底層の色は最上層を通してより視認可能になり、最上層の色は底層を通してより視認可能になる。 The multilayer precursor web, the thinning of a colored web material along the at and / or sidewall distal end of the discrete elongated elements, in the region of the web that is thinned, the color of the web of the bottom layer than through the top layer becomes visible, the top layer of the color is more visible through the bottom layer. 前駆体ウェブの少なくとも1つの表面上に位置する着色剤を含む単層前駆体ウェブについては、離散型伸長要素の遠位端における及び/又は側壁に沿った有色ウェブ材料の薄化により、前駆体ウェブの表面上に配置された着色剤も薄くなるか又は断裂することが可能になり、その結果、前駆体ウェブの単層の色は、着色剤が薄くなっている又は断裂しているウェブの領域において、より視認可能になる。 For monolayer precursor web comprising a colorant which is located on at least one surface of the precursor web, the thinning of a colored web material along the at and / or sidewall distal end of the discrete elongated elements, the precursor it is possible to either or tear even thinner colorant disposed on the surface of the web, so that the color of a single layer of the precursor web is a web that is or torn colorant is thin in the region, the more visible. このことにより、離散型伸長要素により有色ウェブに形成された特定のパターンを強調する有色ウェブの視覚的審美性における対照を提供することができ、審美的に好ましいウェブ材料を作り出すことができる。 Thus, it is possible to provide a control in visual aesthetics emphasize colored web specific pattern formed on the colored web by discrete elongated element, it is possible to produce aesthetically pleasing web material.

異なる屈折率を有するポリマーから作製される層を含む多層ウェブ材料の離散型伸長要素を薄化することにより、薄化領域において各層の屈折特性を変えることができ、これはウェブの視覚的印象を変え、離散型伸長要素により作り出されるパターンを強調するのに役立つことができる。 By thinning the discrete elongated elements of a multilayer web material comprising a layer made from a polymer having a different refractive index, it is possible to alter the refractive properties of each layer in the thin area, which the visual impression of the web changing, it can serve to emphasize the pattern created by the discrete elongated elements. 更に、三次元トポグラフィーは、このような多層ウェブ材料の角度依存性に起因して、伸長要素の見かけの色を異なるものにする。 Furthermore, the three-dimensional topography, due to the angular dependence of such a multilayer web material, to the apparent color of the elongated elements differ. それゆえに、伸長要素の遠位端における及び/又は側壁に沿った薄化がない場合でも、伸長要素から生じる三次元トポグラフィーは、見かけの色変化の視覚的効果を生じることができる。 Therefore, even if there is no thinning along and / or sidewall at the distal end of the elongate element, three-dimensional topography that results from extension element can produce a visual effect of apparent color change.

多層ウェブの特定の実施形態では、下位層(例えば、底層)は、上位層(例えば、最上層)を通過して伸長しない。 In a particular embodiment of the multilayer web, the lower layer (e.g., bottom layer), the upper layer (e.g., the uppermost layer) does not extend through the. この態様では、特に、離散型伸長要素の遠位端が閉口である実施形態では、上位/最上層は、分断又は破壊されず、連続性を維持する。 In this embodiment, particularly, the distal end of the discrete elongated element is closed embodiment, the upper / top layer, not divided or broken, to maintain continuity.

図1は、三次元有色ウェブ18の一実施形態の部分図である。 Figure 1 is a partial view of an embodiment of a three-dimensional colored web 18. 三次元有色ウェブ18は前駆体ウェブから製造され、これは、下記のような、単層のウェブ材料、又は多層の共押出伸長若しくは積層ウェブ材料であることができる。 Three-dimensional colored web 18 is manufactured from a precursor web, which may be as follows, the web material of the single layer or a coextruded stretched or laminate web materials of the multilayer. 図1に示すように、前駆体ウェブは、第一層20と第二層22を含む二層積層フィルムである。 As shown in FIG. 1, the precursor web is a two-layer laminated film comprising a first layer 20 a second layer 22. 多層ウェブ材料の一方又は両方の層は、着色剤を含むことができる。 One or both of the layers of the multilayer web material can include a colorant. 多層フィルム材料は、表面薄層を含むフィルムを包含する積層フィルムを作製するために当該技術分野において既知のように共押出成形されてもよい。 The multilayer film materials may be co-extruded as known in the art for making laminate films include films comprising skin layers.

図1は、有色ウェブ18が複数の離散型伸長要素24を備えることを更に示す。 Figure 1 further shows that the colored web 18 comprises a plurality of discrete elongate element 24. 離散型伸長要素24は、通常はウェブの第一表面上に、ウェブの隆起した伸長部として形成される。 Discrete elongated elements 24, usually on the first surface of the web, is formed as a raised extension of the web. 有色ウェブを形成するために使用される成形構造体に依存して、離散型伸長要素は、ウェブの両面から伸長してもよい。 Depending on the molded structure used to form a colored web, discrete elongate element may be extended from both sides of the web. 有色ウェブ18上の離散型伸長要素24の数、寸法及び分布は、所望される柔らかい感触、音響効果及び視覚的効果に基づいて、予め定めることができる。 The number of discrete elongated elements 24 on colored web 18, the size and distribution, the desired soft feel, based on the sound effects and visual effects can be predetermined. 使い捨て吸収性物品におけるトップシート、バックシート若しくは剥離紙包装材料又は包装などの用途については、離散型伸長要素24は有色ウェブ18の一方の表面からのみ隆起することが所望され得る。 Topsheet in a disposable absorbent article, the backsheet, or release paper packaging materials or applications such as packaging, discrete elongated element 24 may be desirable raised from only one surface of the colored web 18. それゆえに、有色ウェブ18が使い捨て吸収性物品においてトップシートとして使用される場合、有色ウェブ18は、離散型伸長要素24が非常に柔らかい印象で皮膚に接触するように配置することができる。 Therefore, if the colored web 18 is used as a topsheet in a disposable absorbent article, colored web 18 may be discrete elongated elements 24 are placed in contact with the skin with very soft impression. 更に、閉口遠位端26を有する離散型伸長要素24により、再湿潤は減少する、すなわち、トップシートの開口から下部の吸収層に最初に通過した後にトップシートの表面に再導入される流体の量は減少することができる(マクロ開口などの開口が本明細書の図に示されていないことに留意されたい)。 Further, the discrete elongated elements 24 having a closed distal end 26, the rewet decreases, i.e., the fluid being re-introduced to the surface of the topsheet after having passed through the opening of the top sheet in the first absorption layer of the lower the amount can be reduced (like opening such macro opening is noted that not shown in the figures herein).

図2は、本発明の有色ウェブ18の一実施形態の一部の断面図である。 Figure 2 is a partial sectional view of an embodiment of a colored web 18 of the present invention. 図2に示すように、離散型伸長要素24は、有色ウェブ18の第一表面28から隆起しているものとして述べることができる。 As shown in FIG. 2, discrete elongate element 24 may be described as being raised from the first surface 28 of the colored web 18. このように、離散型伸長要素24は、前駆体ウェブ30と一体であり、前駆体ウェブ30の恒久的局所塑性変形により形成されるものとして述べることができる。 Thus, discrete elongate element 24 is integral with precursor web 30 may be described as being formed by permanent local plastic deformation of precursor web 30. 離散型伸長要素24は、開口近位部34及び閉口又は開口遠位端26を画定する側壁32を有するものして述べることができる。 Discrete elongated elements 24 may be described by those having sidewalls 32 defining an open proximal portion 34 and a closed or open distal end 26. 離散型伸長要素24は各々、隣接する伸長要素間の最小振幅A minから閉口又は開口遠位端26における最大振幅A maxまでで測定される高さhを有する。 Each discrete elongated element 24 has a height h which is measured up to the maximum amplitude A max at the minimum amplitude A min closed from or open distal end 26 between adjacent elongated elements. 離散型伸長要素は直径dを有し、これは、ほぼ円筒形の構造について、横方向断面での外径である。 Discrete elongated element has a diameter d, which is the structure of a generally cylindrical, an outer diameter in the transverse cross-section. 「横方向」は、第一表面28の平面にほぼ平行であることを意味する。 "Lateral" means that it is substantially parallel to the plane of the first surface 28. 不均一な横方向断面を有するほぼ円柱状の離散型伸長要素、及び/又は、離散型伸長要素の非円筒形構造について、直径dは、図2に示すように、離散型伸長要素の高さhの1/2における平均横方向断面寸法として測定される。 Substantially cylindrical discrete elongated elements having a non-uniform transverse cross-section, and / or, for non-cylindrical structures of discrete elongate element, the diameter d, as shown in FIG. 2, the height of the discrete elongated element measured as the average lateral cross-sectional dimension at ½ the h. したがって、離散型伸長要素24について、h/dとして定義されるアスペクト比を決定することができる。 Accordingly, the discrete elongated element 24 can determine the aspect ratio, defined as h / d. 離散型伸長要素24は、少なくとも約0.2、少なくとも約0.3、少なくとも約0.5、少なくとも約0.75、少なくとも約1、少なくとも約1.5又は少なくとも約2のアスペクト比h/dを有することができる。 Discrete elongated element 24, at least about 0.2, at least about 0.3, at least about 0.5, at least about 0.75, at least about 1, at least about 1.5 or at least about 2 aspect ratio h / d it can have. 離散型伸長要素24は、典型的には、少なくとも約30マイクロメートル、少なくとも約50マイクロメートル、少なくとも約65マイクロメートル、少なくとも約80マイクロメートル、少なくとも約100マイクロメートル、少なくとも約120マイクロメートル、少なくとも約150マイクロメートル又は少なくとも約200マイクロメートルの高さhを有する。 Discrete elongated elements 24 is typically at least about 30 micrometers, at least about 50 micrometers, at least about 65 micrometers, at least about 80 micrometers, at least about 100 micrometers, at least about 120 micrometers, at least about 150 micrometers, or at least about 200 micrometers has a height h. 離散型伸長要素24は、典型的には、約50マイクロメートル〜約5,000マイクロメートル、約50マイクロメートル〜約3,000マイクロメートル、約50マイクロメートル〜約500マイクロメートル、約65マイクロメートル〜約300マイクロメートル又は約75マイクロメートル〜約200マイクロメートルの直径dを有する。 Discrete elongated elements 24 is typically about 50 micrometers to about 5,000 micrometers, about 50 micrometers to about 3,000 micrometers, about 50 micrometers to about 500 micrometers, about 65 micrometers having a diameter d of about 300 micrometers, or from about 75 micrometers to about 200 micrometers. 一実施形態では、成形構造体10の離散型隆起要素15は、約500マイクロメートル未満の直径を有する。 In one embodiment, discrete raised elements 15 of the forming structure 10 has a diameter of less than about 500 micrometers.

ほぼ非円柱状又は不規則性形状を有する離散型伸長要素について、離散型伸長要素の直径は、高さの1/2で離散型伸長要素の旋回半径の2倍として定義することができる。 For discrete elongated elements having a substantially non-cylindrical or irregular shape, the diameter of the discrete elongated element can be defined as twice the turning radius of the discrete elongated elements at half the height.

ウェブ材料全体にわたって縦方向に伸長し、その結果、伸長要素が、開口である伸長要素の側壁の一部を有する、凸部などの形状を有する離散型伸長要素について、離散型伸長要素の直径は、高さの1/2での伸長要素の2つの対向する側壁の間の平均最小幅として定義することができる。 Extending longitudinally over the entire web material, as a result, elongation element has a part of the side wall of the elongated elements an opening, the discrete elongated elements having a shape such as protrusions, the diameter of the discrete elongated element it can be defined as the average minimum width between two opposite side walls of the elongated elements at half height. 図3は、凸形状である離散型伸長要素を備える有色ウェブを示し、離散型伸長要素は、高さhの1/2で測定された直径dを有する。 Figure 3 shows a colored web with discrete elongated elements is convex, discrete elongated element has a diameter d which is measured at half the height h.

一般に、任意の個別の離散型伸長要素24の実際の高さhは決定することが困難であるため、並びに、実際の高さは変動し得るため、複数の離散型伸長要素の平均高さh avgが、有色ウェブ18の所定の領域にわたって平均最小振幅A min及び平均最大振幅A maxを決定することにより、決定することができる。 In general, because the actual height h of any individual discrete elongated elements 24 are difficult to determine, and, because the actual height may vary, an average height of a plurality of discrete elongate element h avg is by determining the average minimum amplitude a min and an average maximum amplitude a max over a predetermined area of the colored web 18 can be determined. このような平均高さhp avgは、典型的には、上記の高さの範囲内に収まる。 Such average height hp avg typically falls within the above range of height. 同様に、様々な断面寸法に関し、平均直径d avgを複数の離散型伸長要素24について決定することができる。 Similarly, it is possible to determine it relates variety of cross-sectional dimensions, an average diameter d avg for a plurality of discrete elongate element 24. このような平均直径d avgは、上記の直径の範囲内に収まる。 Such average diameter d avg falls within the above range in diameter. このような振幅及び他の寸法測定値は、コンピューターを使用した走査顕微鏡及びデータ処理によるといった当該技術分野において既知の任意の方法で割り出すことができる。 Such amplitude and other dimensional measurements can be determined in any manner known in the art such as by scanning microscopy and data processing using computers. それゆえに、有色ウェブ18の所定の部分についての離散型伸長要素24の平均アスペクト比AR avgは、h avg /d avgとして表すことができる。 Therefore, an average aspect ratio AR avg of discrete elongated elements 24 of the predetermined portion of the colored web 18 can be expressed as h avg / d avg.

特定の実施形態では、離散型伸長要素の高さは、下記のように異なる色又は色相を作り出すために、変動させることができる。 In certain embodiments, the height of the discrete elongated elements in order to create a different color or hue as described below, can be varied. 例えば、離散型伸長要素は、隣接する伸長要素と比較したときに、段階的に増加又は減少する高さを有することができ、これにより、滑らかな色勾配を作り出すことができる。 For example, discrete elongated elements, when compared with the adjacent elongated elements may have a height that increases or decreases stepwise, which makes it possible to create a smooth color gradient. あるいは、隣接する伸長要素又は伸長要素の隣接区域は、高さをより急激に変えることができ、これにより色外観に急激な違いを作り出すことができる。 Alternatively, the immediate area of ​​the adjacent elongated elements or elongated elements, the height can be changed more rapidly and thereby create abrupt difference in color appearance.

一実施形態では、離散型伸長要素24の直径は一定であるか、又は、振幅の増加と共に減少する(振幅は増加して閉口又は開口遠位端26にて最大になる)。 In one embodiment, if the diameter of the discrete elongated elements 24 is constant, or, (maximized by the amplitude increases to a closed or open distal end 26) that decreases with increasing amplitude. 図2に示すように、例えば、離散型伸長要素24の直径又は平均横方向断面寸法は、近位部34にて最大であることができ、横方向断面寸法は遠位端26に向かって一定減少する。 As shown in FIG. 2, for example, the diameter or average lateral cross-sectional dimension of the discrete elongated elements 24 can be a maximum at proximal portion 34, lateral cross-sectional dimension towards the distal end 26 fixed Decrease.

一実施形態では、離散型伸長要素は、米国特許第4,846,821号に記載のものなどの離散型のキノコ状表面段差であることができる。 In one embodiment, discrete elongated element can be a discrete mushroom like surface level difference such as those described in U.S. Patent No. 4,846,821.

図2に示すように、前駆体ウェブ30の所望による薄化は、高いアスペクト比の離散型伸長要素24を形成するために必要とされる比較的深い絞りに起因して、生じる。 As shown in FIG. 2, optional thinning of precursor web 30, due to the relatively deep aperture is required to form a discrete elongate element 24 of high aspect ratio, it occurs. 例えば、薄化は、閉口又は開口遠位端26にて、及び/又は、側壁32に沿って、観察することができる。 For example, thinning, at closed or open distal end 26, and / or along the side wall 32, can be observed. 「観察される」とは、拡大断面図で見た場合に、薄化が明瞭であることを意味する。 By "observation", when viewed in the enlarged cross sectional view, which means that thinning is clear.

このような薄化は、所望によるものではあるが、接触されたときに薄化部分が圧縮又は剪断にほとんど抵抗を示さないことから、柔軟性の観点からは有益であり得る。 Such thinning, albeit due desired, since the thinned portion when contacted exhibit little resistance to compression or shear, may be beneficial in terms of flexibility. 例えば、人が有色ウェブ18の離散型伸長要素24を呈している側に触れた場合に、その人の指先はまず、離散型伸長要素24の閉口又は開口遠位端26に接触する。 For example, when a person touches the side and has a discrete elongate element 24 colored web 18, the fingertip of the person initially contacts the closed or open distal end 26 of discrete elongated elements 24. 離散型伸長要素24の高いアスペクト比、並びに、遠位端26にて又はその近くで前駆体ウェブ30の壁が薄化することに起因して、離散型伸長要素24は、人の指により有色ウェブ上に付与される圧縮又は剪断にほとんど抵抗を示さない。 High aspect ratio of discrete elongated elements 24, and, due to the wall of the precursor web 30 at or near its distal end 26 is thinning, discrete elongated elements 24, colored by human fingers show little resistance to compression or shear is applied to the web. この抵抗の欠失は、ベロア布地の感触に酷似した柔軟な感触に関係する。 Deletion of this resistance is related to the soft feeling that is very similar to the feel of velor fabric.

このような薄化はまた、所望によるものではあるが、薄化領域が薄化していない領域とは異なる視覚的印象を提供できるので、視覚的印象の見地からも有益であることができる。 Such thinning also, albeit due desired, it is possible to provide a different visual impression from the region where the thinned area is not thinned, can also be beneficial in terms of visual impression. 例えば、本発明の前駆体ウェブが二層ウェブであり、最上層と底層が各々異なる着色剤を含み、それゆえに異なる色を呈する場合には、薄化により、有色ウェブの最上面を見た際に底層の色が、より視認可能になる。 For example, a precursor web is double-layered web of the present invention, when the top and bottom layer each comprise different colorants, exhibit a different color therefore, due thinning, when viewed uppermost surface of the colored web the color of the bottom layer becomes more visible. 例えば、これにより、底層が白色又は黒色である場合に、それぞれ、離散型伸長要素を明るく又は暗くすることができる。 For example, thereby, when the bottom layer is white or black, respectively, it can be bright or dark discrete elongate element. あるいは、これは、異なる区域における薄化の程度に依存して、新たな異なる色又は色の組み合わせの伸長要素を作り出すことができ、例えば、青い最上層と黄色の底層を含む二層前駆体フィルムは、緑の伸長要素を作り出すことができる。 Alternatively, this will vary depending on the degree of thinning in the area, it is possible to produce a new different color or colors elongated elements of the combination of, for example, two-layer precursor comprising a bottom layer of blue top and yellow film is, it is possible to produce the green elongated elements. 色変化は、薄化領域における伸長要素の外側及び内側の両方において影響を受ける。 Color change, affected in both the outer and inner elongate element in the thin area. 前駆体ウェブが交互の層で異なる屈折率を有する多層ウェブである場合(例えば、真珠光沢フィルム)、薄化は、青方偏移を生じることができ、あるいは、おそらくは有色前駆体ウェブを無色の伸長要素を有するウェブに転移させることさえできる。 When the precursor web is a multilayer web having a different refractive index in the alternating layers (e.g., pearlescent film), thinning may cause blue shift, or perhaps colored precursor web colorless It can even be transferred to a web having elongated elements. これは、有色ウェブの離散型伸長要素により作り出されるパターンを強調できる独特の視覚効果を提供する点で重要であり得る。 This can be important in providing a unique visual effect of emphasizing the pattern created by the discrete elongated elements colored web.

閉口又は開口遠位端26における及び/又は側壁32に沿った前駆体ウェブの所望による薄化は、前駆体ウェブの厚さに関して、又は、着色ウェブの離散型伸長要素を完全に包囲するランド領域の厚さに関して、測定することができる。 Optional thinning of closed or open distal end 26 in and / or precursor web along the side wall 32, with respect to the thickness of the precursor web, or a land area that completely surrounds the discrete elongated elements colored web it can regard thickness measured. 前駆体ウェブは、典型的には、前駆体ウェブの厚さに関して、少なくとも約25%、少なくとも約50%又は少なくとも約75%の薄化を呈する。 Precursor web is typically respect the thickness of the precursor web, at least about 25%, exhibits at least about 50%, or at least about 75% thinning. 前駆体ウェブは、典型的には、有色ウェブの離散型伸長要素を包囲するランド領域の厚さに関して、少なくとも約25%、少なくとも約50%又は少なくとも約75%の薄化を呈する。 Precursor web typically exhibits respect the thickness of the land area surrounding the discrete elongated elements colored web, at least about 25%, at least about 50%, or at least about 75% thinning.

一般に、有色ウェブ上の離散型伸長要素の高い領域密度(又は低い平均中心間離間距離又は低い平均端部間離間距離)を形成する能力は、前駆体ウェブの厚さにより制限することができる。 In general, the ability to form high area density discrete elongated elements on colored web (or low average center-to-center distance or lower average end between separation distance) can be limited by the thickness of the precursor web. 例えば、一実施形態では、成形構造体の2つの隣接する離散型隆起要素の端部間離間距離は、成形構造体の隣接する離散型隆起要素間の適切かつ完全な三次元有色ウェブ形成を可能にするために、前駆体ウェブの厚さの約2倍を超えるべきである。 For example, in one embodiment, the two ends between the separation distance between adjacent discrete raised elements of the molded structure allows proper and complete three-dimensional colored web formation between adjacent discrete raised elements of the forming structure to, it should exceed about 2 times the thickness of the precursor web. 更に、一実施形態では、成形構造体の複数の離散型隆起要素の平均高さと前駆体ウェブの厚さの比は、典型的には少なくとも約2:1、少なくとも約3:1、少なくとも約4:1又は少なくとも約5:1である。 Furthermore, in one embodiment, a plurality of ratio of the average height and the precursor web thickness of the discrete raised elements of the forming structure is typically at least about 2: 1, at least about 3: 1, at least about 4 : 1 or at least about 5: 1. 同様に、凹部又は開口を有する成形構造体が本発明の有色ウェブを作製するために使用される場合、開口直径は、三次元有色ウェブを形成するために凹部又は開口に適合させるべく、前駆体ウェブの厚さの2倍を超えなければならない。 Similarly, if the forming structure having a recess or opening is used to produce a colored web of the present invention, the opening diameter, to adapt the recesses or openings in order to form a three-dimensional colored web, the precursor It must be more than twice the thickness of the web.

特定の実施形態では、前駆体ウェブは、所望により、界面活性剤を更に含むことができる。 In certain embodiments, the precursor web can optionally further include a surfactant. 利用される場合には、好ましい界面活性剤は、アルコールエトキシレート、アルキルフェノールエトキシレート、カルボン酸エステル、グリセロールエステル、脂肪酸のポリオキシエチレンエステル、アビエチン酸に関連する脂肪族カルボン酸のポリオキシエチレンエステル、無水ソルビトールエステル、エトキシ化(etyhoxylated)無水ソルビトールエステル、エトキシ化天然脂肪、油及びワックス、脂肪酸のグリコールエステル、カルボン酸アミド、ジエタノールアミン縮合体及びポリアルキレンオキシドブロックコポリマーなどの非イオンファミリーからのものが挙げられる。 When utilized, the preferred surfactants are alcohol ethoxylates, alkylphenol ethoxylates, carboxylic acid esters, glycerol esters, polyoxyethylene esters of fatty acids, polyoxyethylene esters of aliphatic carboxylic acids related to abietic acid, They include anhydrous sorbitol esters, ethoxylated (etyhoxylated) anhydrous sorbitol esters, ethoxylated natural fats, oils and waxes, glycol esters of fatty acids, carboxylic acid amide, is from a non-ionic families such as diethanolamine condensates, and polyalkyleneoxide block copolymer It is. 本発明のために選択される界面活性剤の分子量は、約200グラム毎モル〜約10,000グラム毎モルの範囲であり得る。 The molecular weight of surfactants selected for the present invention can range from about 200 grams per mole to about 10,000 grams per mole. 好ましい界面活性剤は、約300〜約1,000グラム毎モルの分子量を有する。 Preferred surfactants have a molecular weight of from about 300 to about 1,000 grams per mole.

利用される場合には、前駆体ウェブ中に最初にブレンドされる界面活性剤濃度は、前駆体ウェブ全体の最大10重量パーセントであることができる。 When utilized, the surfactant concentration to be blended first into the precursor web can be a maximum of 10% by weight of the total precursor web. 好ましい分子量範囲(300〜1,000グラム/モル)の界面活性剤を低濃度で、通常は前駆体ウェブ全体の約5重量パーセント以下で、添加することができる。 At low concentrations of surfactant preferred molecular weight range (300 to 1,000 grams / mole), can be usually up to about 5 weight percent of the total precursor web, it is added.

粒子状皮膚処理剤若しくは保護剤、又は、例えば、ゼオライトといった匂い吸収活性物質などの他の添加剤は、所望により、前駆体ウェブの1つ以上の層に添加することができる。 Particulate skin treatments or protectants, or, for example, other additives such as odor absorbing active substances such zeolite can optionally be added to one or more layers of precursor web. いくつかの実施形態では、粒子状物質を含む有色ウェブは、皮膚接触用途に使用される場合には、活性物質を非常に直接的及び効率的な方法で皮膚に接触させることができる。 In some embodiments, the colored web comprising particulate matter, when used in skin-contacting applications, can be contacted with the skin of the active substance in a very direct and efficient manner. 特に、いくつかの実施形態では、離散型伸長要素の形成は、粒子状物質をその遠位端で又はその近くで曝露することができる。 In particular, in some embodiments, the formation of discrete elongated element may be exposed at or near the distal end thereof particulate matter. それゆえに、皮膚ケア剤などの活性物質は、有色ウェブが皮膚接触用途で使用された場合にこのような皮膚ケア剤との直接皮膚接触を可能にするために、離散型伸長要素の遠位端にて又はその近くにて局所化することができる。 Therefore, actives such as skin care agents, in order to allow direct skin contact with such skin care agents when the colored webs used in skin-contacting applications, the distal end of the discrete elongated element at or may be localized at near.

真珠光沢フィルムもまた、本発明の有色ウェブ材料に好適な前駆体ウェブであることができる。 Iridescent film may also be a suitable precursor web colored web material of the present invention. 真珠光沢フィルムは、典型的には、第一屈折率を有する第一ポリマーを含む第一層と、第二屈折率を有する第二ポリマーを含む第二層と、を含む多層フィルムである。 Iridescent films typically is a multilayer film comprising a first layer comprising a first polymer having a first refractive index, a second layer comprising a second polymer having a second refractive index, the. 各層の異なるポリマーの異なる屈折率は、真珠光沢効果を生じる。 Different different refractive index of the polymer of each layer produces a pearlescent effect. いくつかの真珠光沢フィルムは、百を超える層を含み、各層は厚さがわずか数ナノメートルである。 Some iridescent film comprises a layer of more than one hundred, each layer is only a few nanometers thickness. このような真珠光沢フィルムは、米国特許第3,711,176号及び同第5,451,449号に詳細が記載されている。 Such pearlescent films are detailed in U.S. Patent No. 3,711,176 No. and the second 5,451,449 is described. 好適な市販の真珠光沢フィルムは、BASFから商品名AURORA(登録商標)Special Effect Filmsで市販されている。 Suitable commercially available pearlescent films are commercially available under the trade name AURORA (registered trademark) Special Effect Films from BASF.

本発明の有色ウェブを製造するために前駆体ウェブとして利用される真珠光沢フィルムは、特に興味を引く視覚効果を提供することができる独特の特性を有する。 Iridescent film to be used as a precursor web in order to produce a colored web of the present invention have unique properties which can provide a visual effect of particular interest. 各層における各ポリマーの屈折特性及び真珠光沢フィルムの各層の厚さは、真珠光沢フィルムにより反射される光の波長を決定し、それゆえにフィルムは様々な色を呈する。 The thickness of each layer of the refractive properties and iridescent film of each polymer in each layer determines the wavelength of light reflected by the iridescent films, and therefore the film exhibits various colors. 本発明の有色ウェブを形成するために真珠光沢フィルムを加工すると、有色ウェブの伸長要素は、三次元トポグラフィー並びに/又は本発明の有色ウェブの伸長要素の遠位端における及び/若しくは側壁に沿ったフィルムの薄化に起因して、異なる色及び/又は視覚効果を呈する傾向を有する。 When processing the iridescent film to form a colored web of the present invention, elongated elements of colored web, along and / or sidewall at the distal end of the three-dimensional topography and / or colored web elongate element of the present invention was due to the thinning of the film have a tendency to exhibit different colors and / or visual effect.

一実施形態では、真珠光沢フィルムは、空気の層を含むことができる(例えば、前駆体ウェブ材料内の空隙)。 In one embodiment, the pearlescent film can include a layer of air (e.g., voids precursor in the web material). このようなウェブ材料は、蝶の翅に自然に見られる構造を模倣することができ、翅構造内の空気の層は、ウェブ材料に真珠光沢外観を付与するのに十分な屈折特性の違いを提供する。 Such web material is able to mimic the structure found naturally in wing butterfly, a layer of air in the wing structure, the difference in sufficient refractive properties to confer nacreous appearance to the web material provide.

真珠光沢フィルムの色は角度依存性であるので、伸長要素の三次元トポグラフィーは、フィルム層の薄化がほとんど又は全くない場合(例えば、約25%未満)でさえ、前駆体ウェブ及び離散型伸長要素の周りのランド領域とは異なる視認可能な色を帯びる。 The color of the pearlescent film is angle dependent, three-dimensional topography of the elongated elements, when thinning of the film layer is little or no (e.g., less than about 25%) even, precursor web and discrete It takes on a color different possible viewing from the land area around the elongated elements.

既述のように、真珠光沢前駆体ウェブの外観は、本発明の有色ウェブの伸長要素を形成するときなど、ウェブに付与する薄化の程度により操作することができる。 As already mentioned, the appearance of pearlescent precursor webs, such as when forming the elongated elements colored web of the present invention, can be manipulated by the degree of thinning of imparting to the web. 真珠光沢フィルムが反射光の光路長が約370nm〜約770nmの範囲(すなわち、可視光範囲)内に収まるような、厚さ及び屈折特性を有するとき、フィルムは知覚色を呈する。 Range optical path length is about 370nm~ about 770nm pearlescent film reflection light (i.e., visible light range) to fit within, when having a thickness and refractive properties, the film exhibits a perceived color. 強化される反射色は、層厚さの波長の最大で約2倍の波長を有する。 Enhanced the reflection color has approximately twice the wavelength of the maximum wavelength of the layer thickness. 光がウェブを通して取る光路長は、視角依存性である。 The optical path length which the light takes through the web is a viewing angle dependence. 直接上から(すなわち、90度)見ると、光路長は最短となり、層の厚さの約2倍である。 From the direct (i.e., 90 degrees) when viewed, the optical path length becomes shortest, is about twice the thickness of the layer. 90度未満の角度から見ると、光路長はより長くなる。 Viewed from an angle of less than 90 degrees, the optical path length becomes longer. それゆえに、ウェブの所定の領域の厚さを変えることによりウェブの所定の領域内の知覚色を操作することが可能である。 Therefore, it is possible to manipulate the perceived color in a predetermined area of ​​the web by changing the thickness of a predetermined area of ​​the web. 本発明の有色ウェブの薄化伸長要素を形成することは、伸長要素の領域に知覚色の変化を付与する。 Forming a thinned extension elements colored web of the present invention imparts a change in perceived color in the area of ​​the elongate element. 変化の程度は、ウェブの薄化の程度に依存し得る。 The degree of change may depend on the degree of thinning of the web.

図7A及び7Bは、特定の真珠光沢フィルムウェブであるAurora Special Effect Film IF 4781 Red Green 56における薄化の効果を示す。 7A and 7B show the effect of thinning the Aurora Special Effect Film IF 4781 Red Green 56 is a specific iridescent film web. 未伸張状態の真珠光沢フィルムは、暗色の背景の前であると緑色を呈し、明色の背景の前であると赤色を呈する。 Iridescent film of unstretched state, exhibits a green to be prior to the dark background, it exhibits red and a front light-colored background. 図7Aの真珠光沢フィルムウェブは、暗色の背景に対する未伸張状態で示されている。 Iridescent film web in FIG. 7A is shown in unstretched state for dark background. 図7Aのフィルムウェブは、次に、幅25.4mm、長さ25.4mmのサンプルを2mm/秒の引張試験機で引張ることにより、伸張される。 Film web in FIG. 7A, then, by pulling width 25.4mm, the sample length 25.4mm in tensile tester 2 mm / sec, is stretched. 図7Bに示すように、伸張した真珠光沢フィルムウェブは、薄化していない第一領域と、いくらか薄化した第二領域と、更に薄化した第三領域と、を呈する。 As shown in FIG. 7B, it stretched iridescent film web exhibits a first region which is not thinned, and a second region which is somewhat thinned, and further a third area thinned, the. 第一領域は、図7Aの未伸張状態のフィルムと同一の色を有する。 First region has a same color as the film of the non-stretched state in Figure 7A. 第二領域は、未伸張状態のフィルムに対して視認可能な反射光の青方偏移を生じさせるのに十分に薄化している。 The second region is thinned sufficiently to cause a blue-shift of visible reflected light with respect to the unstretched state film. 第三領域は、十分に伸張した領域において無色であるような程度で薄化している。 Third region is thinned to the extent as is colorless in fully stretched regions. これは、反射光が可視領域外となるように真珠光沢フィルムウェブが薄化している結果である。 This is a result of the reflected light is thinning pearlescent film web such that the visible area outside. すなわち、層の厚さは、最短の可視光波長の半分未満である。 That is, the thickness of the layer is less than half the shortest wavelength of visible light.

厚さの違いは、図8A(緑色を呈する未伸張状態の領域)及び8B(無色外観を呈する伸張状態の領域)に示される断面顕微鏡写真画像により更に例示される。 Thickness difference is further illustrated by the cross-sectional micrograph image shown in FIG. 8A (areas not stretched state exhibited green) and 8B (regions of stretched state exhibiting colorless appearance). 図8Aは、図7Aに示されたフィルムの未伸張状態の有色領域の断面顕微鏡写真画像であり、約150ナノメートルの厚さである各層を有する。 8A is a cross-sectional photomicrograph images of the colored area of ​​the unstretched state of the shown in Figure 7A film having layers of a thickness of about 150 nanometers. 図8Bは、図7Bの、伸張状態の無色第三領域の断面顕微鏡写真画像であり、約80ナノメートルの厚さである各層を有する。 8B is in FIG. 7B, a cross-sectional photomicrograph images of colorless third region of the stretched state, having each a thickness of from about 80 nanometers.

別の実施形態では、真珠光沢前駆体ウェブは、最長の可視光波長の2倍を超える未伸張状態の層の厚さを有することができる。 In another embodiment, the pearlescent precursor web can have a thickness of the layer of non-expanded state of greater than 2 times the longest wavelength of visible light. この場合、フィルムウェブは、最初は無色である。 In this case, the film web is initially colorless. このようなフィルムウェブは、本発明の有色ウェブの伸長要素を形成するときのように、可視光波長に対して真珠光沢を有するような厚さに層を薄化するように、伸張させることができる。 Such film web, such as when forming the elongated elements colored web of the present invention, so as to thin the layer to a thickness such that pearlescent to visible light wavelength, be stretched it can. このとき、フィルムウェブは、薄化領域においてのみ有色になる。 At this time, the film web will colored only in thin area.
